In any triangle on a plane surface, each exterior angle is equal to the sum of the other two interior angles.
Suppose A,B and C are the interior angles and a b and c the corresponding exterior angles.
Then a < 90 implies that B + C < 90
and b< 90 implies that A + C < 90
This gives B+C+A+C < 180 so that A+B+C < 180 which contradicts a property of triangles.

A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
How many acute angles are in an acute triangle?
In an acute triangle, all three angles are acute.
What shape has two acute angles?
There are many possible shapes with two acute angles.
How many acute angles are in a acute triangle?
there are three acute angles in an acute triangle, because there are three corners.
Can a triangle be acute and isosceles?
Yes, that's possible. For instance a triangle with the angles 70°, 70° and 40° is both acute and isosceles.
